This is another older project. The one thing I failed to do at the time was properly research the materials used in the tank. Specifically the brass tubing used for the air line. Brass will leach metals into the water and kill any fish and/or plants. Lucky for me I found this out before putting in any living animals. I’m going to revisit this soon I think and finish it. I’m planing on replacing the play sand with black diamond abrasive (coal slag) as its much heavier and less prone to clouding the water. Plus its black in color so I like the look of it better. I will probably also ditch the filter and have it house some shrimp.
